SHUTTLE.

Specification of Letters Patent.

, Patented Dec. 15, 1914.

Application filed October 2, 1913. Seria1No.-793,027.

To all whom it may concern Be it known that W6,JOHN MrDDLEToN' and useful Improvements in Shuttles, of

Which the following is a specification.

This invention relates to improvements 1n shuttles, and more particularly to the manually threaded type of shuttles.

The object in view is the facilitatlng of hand threading of shuttles for enabling quick and easy accomplishment thereof.

With this and other objects in view, as will in part hereinafter become apparent, and in part be stated, the invention com prises a shuttle body having a gulding slot in one face, and an eye in another disposed at an angle to the plane of the slot, and means extending through the eye and across the slot for guiding yarn from the slot into the eye. I

The invention also comprises a shuttle body having parallel longitudinal slots and a cross connecting slot, one of the slots leading from the bobbin chamber of the body and an eye extending to one side of the body from the other slot, and a guide disposed for directing yarn from the last mentioned slot is an inverted plan View of a shuttle embodying the features of the present invention. Fig. 2 is a view in side elevation thereof. Fig. 3 is a horizontal section taken on the plane indicated by line 33 of Fig. 2 and looking upwardly; Fig. 4c is a transverse vertical section taken on the plane indicated by line 4- of Fig. 1. Fig. 5 is a vertical longitudinal fragmentary section taken on the plane indicated by line 5-5 of Fig. 1. Fig. 6 is a detail fragmentary v1ew illustrating the lateral disposition of yarn during manual threading just prior to drawing the yarn through the yarn feeding aperture.

In the art to which this invention appertains, as is well known, it is customary to thread a shuttle by the employment of a blast of air usually induced by the operator placing his lips to the feeding aperture at the side of the shuttle and sucking through the same, or in some instances produced by blowing through an aperture at the opposite side of the shuttle registering with the yarn feeding aperture. The production of such air blast is accompanied by such unsanitary conditions as to be decidedly detri mental to the health of the operator in addition to the fact that frequently several blasts of air must be employed and sometimes the yarn which has been bunched opposite the feeding aperture becomes entangled so that it must be broken and untangled, or unwound before new yarn can be'threaded, all of which results in loss oftime, and, incidentally, additional expense. These difficulties we propose to fully overcome by the provision of guiding means for causing the yarn to be disposed in the yarn feeding aperture in position for being engaged by the finger of the operator, such disposition being, attained through certain manual manipulations.

In the preferred embodiment the shuttle 1, having bobbin chamber 2, has its head portion formed with the usual laterally disposed yarn feeding aperture 3. The bottom wall of said head is formed with a longitudinal slot 4. leading from the chamber 2 forwardly to a lateral slot 5 which slot leads thence to the forward end of a longitudinal slot 6 arranged. substantially parallel to the slot 4-, and, ofcourse, extending longitudinally ofthe shuttle. The two slots land 6 with the cross slot 5 produces a tongue 7 of the material of the shuttle whose forward end is provided with an upstanding head or extension 8, the slot 5 extending along the head and beneath the same and terminating in the opening or chamber 9 which communicates with the slots 4 and 6 at the rear of the head or inner end of the slot 6. A guiding rod or-bar 10 has its inner end fixed to the projection 8 and extends laterally across a portion of the chamber 9 and out through the aperture 3 and has its outer end fixed to the side of the shuttle 1. Thus the rod 10 extends on an incline across the slot 6, as best seen in Fig. '3, so as to direct a loop of yarn laterally from the slot out through the aperture 3 when the yarn is drawn along the slot into contact with the guiding rod 10.

In operation, the slots 4, 5 and 6 being in the bottom of the shuttle, the operator passes the yarn 11 of a new bobbin through the lower opening of the bobbin chamber and then applies the bobbin onto the spindle and thereafter springs the spindle back into place in the shuttle so that the yarn of the new bobbin is exposed below the shuttle and draws it forwardly along the slot a,

passes it laterally along slot 5, and then draws it rearwardly along slot ,6 until a loop is formed about the guiding rodlO which loop is directed by said rod laterally to be sufficiently exposed at the side of the shuttle to enable the operator to catch. the loop of yarn with the end of his finger and draw the same outwardly; whereupon the shuttle is threaded with the yarn disposed as indicated clearly in Fig. As a further precaution against accidental dislocation of the yarn the forward portion of the slot in the upper face of the shuttle leading from the bobbin chamber is provided with a cross bridge 12. The bridge 12 is disposed to prevent vertical movement of the yarn or looping thereof vertically out through the slot of the bobbin chamber during operation such as might otherwise occur during the rapid throw ofthe shuttle. It is noted that this bridge in no way interferes with the threading of the shuttle as the operation of threading occurs at the opposite or under face of the shuttle.

Having thus described the invention, what is claimed as new is:

1. In a shuttle, the combination with a shuttle body having a bobbin chamber, the chamber having a portion extending beyond the bobbin and having a substantially closed bottom and open top beyond the feeding end of the bobbin, a feed aperture being formed through the side wall of the extended portion of the chamber, the bottom of the chamber being formed with a guiding slot for directing yarn into the feed aperture,-

and a bridge extending across and trans-' versely closing the top of the extendedv portion of the chamber above the yarn guiding slot. i

1 2. A shuttle comprising a body 'havingca lateralyarn feeding aperture, and a slot extending from the bobbin chamber of the shuttle past the aperture, and a rod fixed to the outer face of the shuttle and extending through the aperture and acrossthe slot.

8. In a shuttle, "the combination of a shuttlebody having a longitudinal slot extending from the bobbin chamber along the bottom of the shuttle, a slot formed in said bottom and extending substantially parallel to the first slot a cross slot connecting the said slots and having an intercommunicating chamber between "the'slots spaced from the crossslot, said slots forming a tongue, the shuttle having a lateral opening communicating with the second mentioned slot adjacent to the intercommunicating chamher, and a guiding rod secured at one end to the outer wall of-the shuttle adjacent to the opening and at its inner end to the tongue aforesaid, said rod extending through said aperture and into said intercommunicating chamber for directing yarn laterally through the aperture. I

In testimony whereof we aflix our signatures in presence of two witnesses.
